Sirena 38 Information, Review, Specs

Sailing Performance & Handling

The sailing characteristics of the Sirena 38 are defined by its high ballast ratio and its sleek, IOR-influenced (International Offshore Rule) profile. With a beam of only 3.10 meters (approximately 10.2 feet) on a 38-foot hull, the boat is exceptionally narrow by modern standards. This geometry allows the vessel to slice through chop with minimal slamming, offering a remarkably smooth motion in a seaway. According to technical records from Södergren Yacht Design, the boat was engineered to excel upwind, utilizing a deep fin keel and a large fractional rig that provides significant power in light to moderate airs.

Handling is often described as "sensitive" and "rewarding" by long-term owners. Because the boat carries nearly 45% of its weight in the keel, it is exceptionally stiff, allowing it to carry full sail longer than its contemporaries. The fractional rig—featuring a large mainsail and relatively small headsails—makes the boat easier to manage for short-handed crews, as the primary power comes from the main rather than a massive, overlapping genoa. Tracking is reported to be excellent due to the deep spade rudder, though the narrow hull requires active trimming to keep the boat at its optimal heel angle.

Interior Comfort & Variations

Inside, the Sirena 38 reflects the high-water mark of Finnish boatbuilding, characterized by extensive use of warm teak and a layout that prioritizes safety at sea. The headroom is generous for its era, reaching roughly 1.85 to 1.90 meters in the main saloon. The layout is traditional: a V-berth forward, an L-shaped galley to port, and a dedicated navigation station to starboard. Most models were delivered with a double aft cabin tucked under the cockpit, though the narrow beam means this space is more utilitarian than the "palatial" aft cabins found on modern wide-stern yachts.

The quality of the joinery is a frequent point of praise in regional reviews, such as those historically found in the Finnish publication Vene-lehti. The storage is optimized for long-range cruising, with numerous lockers and cubbies integrated into the hull sides. While the interior feels more confined than a modern 38-footer, the security provided by the narrow cabin sole and ample handholds makes it a superior environment for cooking or moving about while the boat is significantly heeled.

Known Issues & Buyer’s Checklist

Prospective buyers of a Sirena 38 should focus on the specific aging points of high-performance 1980s Scandinavian builds.

• Deck Core Integrity: Like many vessels of this era, the Sirena 38 utilizes a balsa-cored deck. Buyers should use a moisture meter around stanchion bases and chainplates to check for delamination or water ingress, which can lead to soft spots.
• Keel-to-Hull Joint: Given the boat’s performance nature and deep draft, the keel bolts and the surrounding fiberglass grid should be inspected for "smile" cracks or signs of hard grounding, which can compromise the structural integrity of the high-load bilge area.
• Saildrive Seal: Most units were originally equipped with Yanmar or Volvo Penta engines utilizing saildrives. If the rubber diaphragm seal has not been replaced within the last 7–10 years, it is a critical maintenance item that requires pulling the engine or drive unit.
• Rudder Bearings: The deep spade rudder is subject to significant leverage. Owners often report the need to replace the original bearings to eliminate play in the steering system, particularly after decades of high-stress offshore use.

Community & Resources

The Sirena 38 maintains a dedicated following in Northern Europe and the Baltic Sea. Technical support is primarily found through the Södergren design community. While no singular international "Sirena Owner’s Association" exists, the boat is frequently discussed in Finnish and Swedish sailing forums where technical drawings and original specifications are shared. Owners looking for original design insights often refer back to the Södergren Group, which remains an active force in naval architecture.

The Verdict

The Sirena 38 is a "sailor’s sailboat," favoring speed, aesthetic elegance, and upwind prowess over interior volume. It is an ideal vessel for the cruiser who prioritizes the journey and the feel of the helm over dockside entertaining.

Pros:

• Exceptional Upwind Performance: Slices through head seas with ease and maintains high pointing angles.
• Timeless Aesthetics: The slender hull and low-profile coachroof remain among the most beautiful designs of the 1980s.
• Build Quality: Finnish craftsmanship ensures a robust hull and a high-quality interior that ages well if maintained.

Cons:

• Limited Interior Volume: The narrow beam makes the salon and aft cabin feel cramped compared to modern 38-foot yachts.
• Aging Systems: Original wiring and plumbing usually require comprehensive updates for modern cruising needs.
• Deep Draft: The performance-oriented keel limits access to shallow anchorages and certain coastal waterways.
